PROBLEM TO BE SOLVED: To provide a drainboard for freezing facilities which has large cooling capacity and also never breaks by shock. SOLUTION: Blocks 4 in the shape of quadrangular tubes are coupled with one another side by side at regular pitches by coupling legs 5, and the whole is molded by extrusion processing of aluminum alloy. Accordingly, chill circulates smoothly inside the block part 4 and in the space between the blocks 4, and since the heat conductivity is large, the drainboard has a large cooling capacity. Then, it never breaks even by shock because it is made of aluminum alloy.
